Which one is the Best Whey Protein for BodyBuilding Go for reputed brands that have been tested for quality. Also check the protein content per scoop of the product. Protein is the building block of the body and is made of amino acids. Some amino acids called EAAs are known as Essential Amino Acids and cannot be created by the body. They need to be got from the diet. Bodybuilders need a supplement that is easy to absorb and that is absorbed easily. Thus, whey concentrate is not a good option since it has less protein and takes longer to digest. You can opt for whey hydrolysate or whey isolate. Ways to select the best whey protein for bodybuilding: Ingredients: Check for additives in the product. Some brands add chemicals like artificial sweeteners, colors, flavours, emulsifiers, thickeners, preservatives, etc. that are not good for health. Avoid high additive products. Fake Products: They contain fillers, steroids, sugar, hormones, etc. They are not healthy and can cause side effects. Always buy from authentic dealers and check the seal or hologram. You can also check the site for the barcode. Allergies: Lactose intolerant people need to be careful while taking whey protein as it is made from milk. Some products contain soy, and those allergic to it should not have it. Milk Shakes: Having a protein powder with milk can lead to side effects like stomach ache, bloating, heaviness, loss of hunger, etc. It can also make you put on weight since milk contains fats. Excess Protein: If you have more protein than you need, it can lead to stress on the kidneys. It can cause protein toxicity that is harmful to your health.
